How does a Raman pump work in the 1830 specific implementation?

Show Suggested Answer Hide Answer
Suggested Answer: D

In Raman amplification, a pump laser is used to excite the Raman-active molecules in the fiber, which then amplifies the signal light as it travels in the opposite direction. In the 1830 specific implementation, the pump laser is typically a high-power laser that is launched into the fiber in the opposite direction to the signal. The pump light interacts with the Raman-active molecules in the fiber, which then amplifies the signal light as it travels in the opposite direction. This allows the Raman pump to provide a gain that increases with distance, which can be used to compensate for the loss of signal power as it travels through the fiber.

D, definitely D. Although, I do wonder if the 1830 implementation is some sort of ancient technology. *chuckles*

B) As the incoming signal power increase, the gain of the amplifier is reduced.

I'm not sure, but I think the answer might be A, where amplification is done simultaneously for all channels.

D is the way to go, no doubt. The pump light traveling in the opposite direction just makes more sense for amplification.

I agree with Meghann, because the pump light travels in the same direction as the signal.

Wait, is this a trick question? I'm going to go with D, but part of me feels like there's a catch.

Hmm, I'm torn between C and D. I guess I'll go with D, since it seems more intuitive for the pump light to travel against the signal.

C sounds good, but D makes more sense to me. The pump light going in the opposite direction seems more logical for amplification.
